What is the advisability of using One Drive or its equivalent as a primary file storage? I am considering using this combined with a portable HDD and SyncBack to allow work my frequent travel to locations with limited or nonexistent internet. I also need to sun the same catalog on 3 different computers not on a server I could then sync changes to the cloud at night or when I get access to the internet. I understand from previous posts that synchronization is time consuming. Is the mirroring function on import enough to populate the HDD with the ingested photos at the same time as the One Drive reference storage? Any suggestions.
